What is ACES?
The Academy Color Encoding System (ACES) is becoming the industry standard for managing color throughout the life cycle of a motion picture or television production. From image capture through editing, VFX, mastering, public presentation, archiving and future remastering, ACES ensures a consistent color experience that preserves the filmmaker’s creative vision. In addition to the creative benefits, ACES addresses and solves a number of significant production, post-production and archiving problems that have arisen with the increasing variety of digital cameras and formats in use, as well as the surge in the number of productions that rely on worldwide collaboration using shared digital image files.

Arri: Working With ACES
ACESCentral - The official hub for ACES users
Firstly you need the OCIO implementation of ACES. The acronym means Academy Color Encoding System/Specification, so it is not a software, but Houdini and Clarisse can handle any colour management system which is implemented in OCIO.
- Download OCIO ACES colour management system:
- Click "Clone or download" and then "Download ZIP" (sorry, but the silly github doesn`t allow to get just the stuff you need from the web interface)
- Extract the latest version folder you find in the ZIP but without the "baked" folder inside, we really don`t need this huge data for Clarisse or Houdini (these are baked LUTs for other softwares... there is a Houdini folder, but for older versions...).
If you have Nuke, you actually have the ACES OCIO 1.0.1, so you just have to do the next step. If you want to use the one installed with Nuke just go it`s install folder, and you can find from in the "/plugins/OCIOConfigs/configs/aces_1.0.1/"
And yes, you can see that there is the "baked" folder, the unnecessary payload, so you can free up around 600MB by removing it, to make Nuke install more lightweight. Of course Nuke should work with ACES without this folder, I tested it, but maybe in some cases, for some reasons you will need it, so just delete it at your own risk (or remember to restore from github, if you really need it).
ACES setup in Houdini
- In the Houdini preferences folder you can find the Houdini environment config file:
Open this file with a text editor.
- Put a new line at the bottom:
OCIO = " the path to the OCIO config file, like ...../ACES_1.0.3/config.ocio , with quotes "
